Email & SMS Marketing

Email and SMS shouldn't feel like a gamble.
They should feel like money well spent.

I'm Janine Karla, a lifecycle marketer who rebuilds flows, segmentation, and campaign strategy on Klaviyo and Attentive so retention becomes your most predictable revenue channel — not your most neglected one.

Case study — the jewelry store

Product · Diamonds & engagement rings Audience · US and international Channels · Klaviyo (email) + Attentive & SMSBump (SMS)

The problem

Two years in business, but email was an afterthought: campaigns went to the full list with no segmentation, flows still ran on Klaviyo's default templates, and the homepage had no pop-up, fly-out, or embedded sign-up form — so paid traffic had nowhere to go.
